1*0f6d785cSDamien RiegelTS-4800 FPGA interrupt controller 2*0f6d785cSDamien Riegel 3*0f6d785cSDamien RiegelTS-4800 FPGA has an internal interrupt controller. When one of the 4*0f6d785cSDamien Riegelinterrupts is triggered, the SoC is notified, usually using a GPIO as 5*0f6d785cSDamien Riegelparent interrupt source. 6*0f6d785cSDamien Riegel 7*0f6d785cSDamien RiegelRequired properties: 8*0f6d785cSDamien Riegel- compatible: should be "technologic,ts4800-irqc" 9*0f6d785cSDamien Riegel- interrupt-controller: identifies the node as an interrupt controller 10*0f6d785cSDamien Riegel- reg: physical base address of the controller and length of memory mapped 11*0f6d785cSDamien Riegel region 12*0f6d785cSDamien Riegel- #interrupt-cells: specifies the number of cells needed to encode an interrupt 13*0f6d785cSDamien Riegel source, should be 1. 14*0f6d785cSDamien Riegel- interrupts: specifies the interrupt line in the interrupt-parent controller 15
